- provide a parachute or glider of the type aboveset forth wherein the wing or plane at each side of the body is formed of hinged sections with a strap and hand clamping device carried bythe section for attachment. to the upper arm and hand of a person, spring hinges connecting the sections of each plane with the sections retained in an open operative position by the hand clamp, the latter being manually operable for releasing' the outer section of the plane or 'wing to permit automatic collapsing or folding movement thereof when desired.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings andclaimed.

' In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a top plan view of the parachute or glider "constructed in accordance with the present invention, the side planes or wings being operativel positioned .upon

a erson and attached to .t e body and arms,

igure 2 shows bottom plan views of two side win or planes, Figure 3 is an edge elevational view of the ' one of the planes in its folded position, and

Figure 4 is a fragmentary bottom plan 'view showing the manually operable hand gripping device in its released position to permit folding of the wing sections.

The parachute or glider comprises a pair of side wings or planes of identical construction 'and each wing is formed of a air of sections 1 and 2 hinged together at t eir longitudinal meetin edges by hinges 3 that norma y cause the wing sections 1 and 2 to assume a folded or collapsed position as shown in Fig.3 with the sections superposed and so retained by the to the clampin strap spring spring clips 4carried by the forward ends of the wing section 2 engaging the adjacent edge of thewing section 1 as shown. The wings .are formed of any suitable material, such as aluminum or the like and the forward ends thereof comprised of continuous sheets whilethe rear tailends of the wings are constructed in simulation of bird. feathers and comprise strips 5 connected together by brace bars 6 and 7 carried by each of the sections 1 and 2, the brace bars 7 being hinged together as at 8 at their meeting ends as shown in Figs. land 3.

The wings. being attached to the outer sides of the arms .of a person as shown in Fig.v 1, 'each intersection. 1 carries a 'pair of cooperating straps 9 upon the lowen'face thereof for encircling the arm 10 illusrtated by dotted lines in Fig. 1, the inner'ed'ges of each section 1 having a cutout P01171011, 11 to intimately contact the arm. A breast and back strap 12 and 13 respectively car- Iried by the win'g'sections 1 at opposite sides of the cutaway portion 11 engage the person as shown in 1 to support the parachute in position. ith the side wings or planes in positionupon a person as shown in Fig. 1 and it being desirable to hold the outer sections 2 of the wings in their extended operative positions above the arms and hands of the person and against tension of the spring hinges 3, devices are carried by the lower face of each outer section 2 for releasably clamping the hand .of the person. and to be so retained by the outstretched arms; 1

The hand gripping. devices are shown more clearly in Figs. 2, 3 and 4, the curved hand engaging straps 14 bei hi 8 J'- supported at one end at 15 to the bracket 16 carried by the outer wing section 2, the other free end of the clamping strap 14 carrying a finger grip 17 that is engaged by the tenstrap 14 in its closed and locked tion 19 attached at one end at 20 to the wing. section 2 has its outer end secured as at 21 14 adjacent its hinge mount1ng 15, t e sprmg 19.being positioned for either holding the clamping strap 14 in 'sioned keeper 18 to retain the clamping its closed position and when said clamping" is moved to an openposition rear-' strap1 war y of the hinge mounting 15, the

.spring also tends to retain the clamping straggn an open position as shown in Fig. i '4.

devices for releasing the clamping strap .14 include a bell crank lever 22 pivotelly mounted as at 23 upon the wing section 2 with one leg?! thereof having a link connection '25v wit the clamping strap '14 while an operating link 26 for the bell crank f lever 22 is attached to the outer end, of'the other leg thereof and is slidable thru a. guide 27 withthe terminal end 28 thereof tioned-in proximity to the finge rs o the band clamped by the straps 14. The coil spring 29 attached -at"one end' to the offset portion 30 of the sliding link 26 with the other end thereof attached as at 31 to the win section 2 normally holds the freeend oft e leg 24 of the bell crank in its forward direction toward the clamping "strap 14. The mannerof wearing the parachute or glider is clearly illustrated in Fig. 1,'the

side wings or planes being disposed outwardly of and above the arms of a per-" son and mounted in position by the arm straps 9 and the chest and back straps'12 operating ro or link 26 at the forward end. ged by the fingers of the-per-' son. for shifting the same against the tenlever 22 an during 1 sustaine and 13. The clamping straps 14 en a ing the hand of the person as illustrated y iob ted lines in Fig. 1 retains the outer wing sections 2 in'their extended operative positions during flight. Whenitis" desired .to release the outer wing sections 2 to be folded upon the inner wing sections 1 and for removing the arachute from ,the body,'the

thereof is e sion of the s 29- to'move the'bell crank thru the medium of the link connection 25 between thebell crank lever and clamping strap 14 release the latter -from the retaining clip 18 tothe position shown. in F 4 and 'at which time the spring 19 wi I retain the clamping strap in its open position while the spring hinges 23 will automatically shift the outer wing sections 2 into thejfolded position shown m Fig. 3. The side wings may-be manipulated flight in simulation of the wings of a; rd and the. general outline of each w ng or lane being similar to a birds wing,

d flight is easily attainable.
